Fallout: New Vegas Gun Guide - Tesla Cannon
The idea of anti-tank weaponry has always had a rare appearance in Fallout except maybe in Tactics but it is fair considering how few tanks the average Courier encounters but still we always have the missile launcher. And that also has a few problems, it is heavy with heavy ammo but the people of the Old World came up with a better, lighter solution, the Tesla Cannon. Enhanced by post-war scientists it is an even more powerful weapon.
